BANAGAN, OF Q'UEOI-IEE, VERMONT WEET END REMOVERFOR'A'UTOMATIC LOOMS .Application led November The present inventionrelates generally to automatic looms and more particularly to means forpreventing end portions'of the lilling extending from and ejected bobbinfrom being drawn into the shed on the first pick of the shuttle after atransfer has been made.

An important object ofthe invention is to provide7 in a manner ashereinafter set forth, a device of the aforementioned char- 1`0 acterembodying a rotary brush which is associated with t-he lay of the loomin a manner to engage with the shuttle when said shuttle leaves its boxon the first pick after a transfer has been made for removing thetrailing end portion of thelilling from the ejected bobbin from the eyeand side of the shuttle. Y

Another important obj ect of the invention is to provide a mechanism ofthe character `2`0 described embodying novel means for `driving therotary brush from the picker ball shaft of the loom, the brush beingmounted for swinging movement with the lay-of the loom.

Another important obj ect of the invention is to provide an apparatus ofthe character set forth embodying novel supporting means for the rotarybrush whereby said brush may be adjusted toward or away from the shuttle3o box should it be so desired;

Other objects of the invention are to provide7 in a manner ashereinafter set forth7 a weft end remover for automatic looms which willbe simple in construction, strong, du-

rable, cliicientand reliable in operation and which may be manufacturedand installed on conventional looms without materially altering saidlooms structurally at low cost.

All of the foregoing and still further objects and advantages of theinvention may become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and

wherein:

Figure 1 is a view principally in front elevation and partly in verticalsection of an apparatus in accordance with this invention mounted inoperative position on a loom. Through the medium of the slot 16; the

Serial N o. 494,136.

Figure 2 is a vertical cross sectional view taken ure 1 substantially onthe line 2-2 of Figlooking in the directionl indicated by the arrows.

Figure 3 is a vertical cross sectional view taken ure 1 substantially onthe line 3-3 of Figlooking in the direction indicated by the arrows.

Figure 4 is a fragmentary View in top plan looking downwardly from theline 4 4 in Figure 1. Figure 5 is a detail view in perspective showi ngthe adjustable brace or strut through the medium of which the rotatablebrush may be adjusted.

Referring to the drawings in detail, it will be seen that the referencenumeral 1 designates a lay having a shuttle box 2 at the replenishingside of the loom, said lay being provided with an elongated slot oropening 8 for the passage of a bobbin or the like 4 which is ejectedfrom the shuttle 5 when saio shuttle is in the box 2 by the transferrer6.

substantially U-shaped bracket 7 is mounted for swinging adjustment onthe lay 1 through the medium of suitable anchoring pins or the like 8which pivotally connect tie upper ends of the arms of the bracket 7 toopposite sides of the lay 1. A horizontal shaft 9 is journalled in thearms of the bracket 7 and has fixed on one end portion a.y gro ovedpulley 10. A circular brush 11 is fixed on an intermediate portion ofthe shaft and s 9 between the arms of the bracket 7 aid brush isoperable in one end porbrack et 7 and said brace or strut 12 is furtherprovided with an angular slotted portion 14 adapted to be adjustablysecured to the lower side of the lay 1 through'the medium bolt throu lay1.

lof a suitable bolt or. the like 15. The or theV like 15, of course,extends gh the slot 16 and is anchored in the bracket 7 may be swung ina vertical plane to adjust the brush 11 relative to the lay 1, as willbe apparent.

A hanger 17 depends from the lower side of an intermediate portion ofthe lay 1 and has fixed on a lower portion thereof an angular bracket18. A shaft 19 extends between the free ends of the hanger 17 and thebracket 18 and has mounted thereon a three step pulley 20.`V Asubstantially U- shaped bracket 21 is anchored on av lower' or othersupport and has extending between the upper end portions of its arms arod 22 upon which is mounted for swinging movement a substantiallyU-shaped member 23fhaving the freeY end portions of its arms vapert'uredfor the passage of the rod 22. A sha-'ft 24: is mounted between the armsof the member 23 and journalled on the shaft 24 at spaced points are thegrooved pullays 25.

A grooved pulley 26 is fixed on the rotary shaft 27 of the automaticloom. An yendless belt 27 is trained around the pulley 26 and has itsflight trained under the pulleys on the swingable member 23, said belt27 then being trained over one of the elements of the pulley 2O as'maybe apparent, the swingable member 23 thus constitutes a gravity actuatedbelt tightener which maintains the proper tension on the belt 27 at alltimes and permits swinging movement of the pulley 20 and the hanger 17with the lay 1 of the loom. The pulley 2O is operatively connected withthe pulley 10 which drives the rotary brush 11 by an endless belt 28.

In operation,` the brush 11 is driven from the shaft 27 of the loomthrough the medium of the endless belts 27 and 28 and the variouspulleys with whichv the belts .are operatively connected'. Vhen atransfer has been made and the ejected bottom o-r the like ldrops intothe usualcan provided for the purpose, the rotary brush 11k will engagethe end 29v of the filling when the shuttle passes saidbrush on thefirst pick in a manner to remove the Vend 29 from the side and eye ofthe shuttle and thus prevent theend from being carried intoV the shed. Y

As before explained, the brush 11 may be adjusted relative to the lay 1and the shuttl'e 5 through the medium of the` swingable supportingbracket 7 and the adjustable brace or strut 12. Y 1- t isv believed thatthe many advantages of ai weft end removerfor` automatic looms, inaccordance ,with .thisinvention will be readily understood, and althoughthe preferred embodiment of the invention is as illustrated anddescribed', it is to be understood that 'ch-anges in the'd'etails ofconstruction may be had which will fall within the scope of theinvention' as claimed.
